  The GNU C++ Library is part of GCC and follows the same development model,
  so the general rules for
  <a class="link" href="http://gcc.gnu.org/contribute.html" target="_top">contributing
  to GCC</a> apply. Active
  contributors are assigned maintainership responsibility, and given
  write access to the source repository. First-time contributors
  should follow this procedure:

	  Get and read the relevant sections of the C++ language
	  specification. Copies of the full ISO 14882 standard are
	  available on line via the ISO mirror site for committee
	  members. Non-members, or those who have not paid for the
	  privilege of sitting on the committee and sustained their
	  two meeting commitment for voting rights, may get a copy of
	  the standard from their respective national standards
	  organization. In the USA, this national standards
	  organization is
	  <a class="link" href="https://www.ansi.org" target="_top">ANSI</a>.
	  (And if you've already registered with them you can <a class="link" href="https://webstore.ansi.org/standards/iso/isoiec148822014" target="_top">buy

      Historically, the libstdc++ assignment form added the following
      question:
    </p><p>
      <span class="quote">“<span class="quote">
	Which Belgian comic book character is better, Tintin or Asterix, and
	why?
      </span>”</span>
    </p><p>
      While not strictly necessary, humoring the maintainers and answering
      this question would be appreciated.
    </p><p>
      Please contact
      Paolo Carlini at <code class="email">&lt;<a class="email" href="mailto:paolo.carlini@oracle.com">paolo.carlini@oracle.com</a>&gt;</code>
      or
      Jonathan Wakely at <code class="email">&lt;<a class="email" href="mailto:jwakely+assign@redhat.com">jwakely+assign@redhat.com</a>&gt;</code>
      if you are confused about the assignment or have general licensing
      questions. When requesting an assignment form from
      <code class="email">&lt;<a class="email" href="mailto:assign@gnu.org">assign@gnu.org</a>&gt;</code>, please CC the libstdc++
      maintainers above so that progress can be monitored.

      <a class="link" href="https://gcc.gnu.org/gitwrite.html" target="_top">Getting write access
	(look for "Write after approval")</a>
    </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="list.patches"></a>Submitting Patches</h3></div></div></div><p>
      Every patch must have several pieces of information before it can be
      properly evaluated. Ideally (and to ensure the fastest possible
      response from the maintainers) it would have all of these pieces:
    </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
	  A description of the bug and how your patch fixes this
	  bug. For new features a description of the feature and your
	  implementation.
	</p></li><li class="listitem"><p>
	  A ChangeLog entry as plain text; see the various
	  ChangeLog files for format and content. If you are
	  using emacs as your editor, simply position the insertion
	  point at the beginning of your change and hit CX-4a to bring
	  up the appropriate ChangeLog entry. See--magic! Similar
	  functionality also exists for vi.
	</p></li><li class="listitem"><p>
	  A testsuite submission or sample program that will
	  easily and simply show the existing error or test new
	  functionality.
	</p></li><li class="listitem"><p>
	  The patch itself. If you are using the Git repository use
	  <span class="command"><strong>git diff</strong></span> or <span class="command"><strong>git format-patch</strong></span>
	  to produce a patch;
	  otherwise, use <span class="command"><strong>diff -cp OLD NEW</strong></span>. If your
	  version of diff does not support these options, then get the
	  latest version of GNU diff.
	</p></li><li class="listitem"><p>
	  When you have all these pieces, bundle them up in a
	  mail message and send it to libstdc++@gcc.gnu.org. All
	  patches and related discussion should be sent to the
	  libstdc++ mailing list. In common with the rest of GCC,
	  patches should also be sent to the gcc-patches mailing list.
